Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applicable to a place where a truck crane cannot be approached and construction is difficult, for example, in a small place such as a pit, a road, a railway overpass or the like. The present invention relates to a method for installing a box culvert from transport of the box culvert to installation. 2. Description of the Related Art Conventionally, a technique for mounting a box culvert by lifting a truck crane has been known. However, since a truck crane is large, it is small and is difficult to install in a pit, a road, a railway overpass or the like. I ca n’t approach the place,
It was not suitable for installation such as installation of a box culvert in a small place. For this reason, without using a heavy truck crane, there has already been proposed a technique for installing a box culvert by using an installation machine that is installed from the outside of the side wall of the box culvert while holding it with set bolts. No. 814432). [0003] However, the installation machine applied to the known box culvert installation technique using an installation machine having set bolts is applied from the outside of the side wall of a square tubular box culvert. The width of the foundation including the wheels for traveling is wide because of the provision of the set bolts, and it cannot be adopted in a narrow construction place where the foundation width cannot be widened. The present invention has been made in view of the above-mentioned problems of the conventional rectangular tubular box culvert installation technology, and enables the box culvert to be laid even in a small place where a wide base installation machine cannot be applied. It is an object of the present invention to provide a method of installing a box culvert. [0005] The present invention has been made to solve the above problems, and employs the following technical means. The invention according to claim 1 is such that the bottom plate of the box culvert, which is composed of a bottom plate and a top plate having an opening formed in the center, and two side plates connected to these plates, moves into and out of the center opening of the bottom plate of the box culvert. A support member comprising one possible wheel and two wheels which are rearwardly spaced from the wheel and which are positioned laterally outside of the box culvert and within its width, and a vertically movable lifting member within the box culvert Enter the installation machine installed in the range in which the support member can abut on the bottom plate upper surface of the box culvert, and after positioning it, lift the box culvert by operating the lifting member of the installation machine, raise the box culvert bottom plate upper surface. After contacting and holding the lower surface of the support member, move to the laying site,
This is an installation method of a box culvert characterized by being installed. DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a special box culvert having a bottom plate having a bottom plate having an opening formed in the center. The lifting member of the installation machine, in which a plurality of rings and a lifting member movable up and down and left and right located in the width thereof outside the box culvert are installed on the support member,
The box culvert is lifted inside the box culvert and the upper surface of the bottom plate of the box culvert is held in contact with the lower surface of the support member so that the box culvert can be moved, laid and installed even in a small place where the construction is difficult.
